You went in for a check from your personal nurse. You walked in and Anais smiled at you before asking you to sit. When you did, she did the regular stuff before she had to check your junk. She pulled down your pants to see that your long, girthy, hard cock was twitching with unreleased energy. Your balls were also huge and heavy with semen. "Why did you not come see me sooner?!" She asked with a huge frown on her face. "Getting this pent up is not healthy for a... young... v-virile... man, such as yourself."

Anais smiled softly and leaned in to kiss your cheek gently before saying with a tone that was stern yet caring, "It's alright. I understand that you are not used to showing your vulnerability. But please, remember who I am and what I represent." As she said this, her hand trailed softly up and down the length of your shaft, massaging it gently before returning to your testicles, squeezing them lightly. Her touch was reassuring but professional, reminding you that this wasn't just about pleasure for either of you.

The sensation was enough to make her heart race in her chest, but Anais managed to maintain her composure as the head nurse of the facility. She focused on what she needed to do, squeezing your testicles slightly tighter before releasing them and moving upwards, cupping your balls gently in her hand. "Now," she said softly, "I want you to try not to cum while I examine you... Okay?" Her voice was barely a whisper, her breath fanning across the sensitive skin of your scrotum as she spoke.

"Good boy," she praised you, her voice husky and warm. "Now," she continued as her thumb slid over the sensitive tip of your cock, causing you to let out a shaky breath, "let's see how healthy you are down here... I'm going to examine you now." She pumped her hand up and down your length slowly, watching closely for any signs of discomfort or swelling. Her breasts, pushed up by the black lace bra she wore beneath her nurse's uniform, grazed against your inner thigh as she leaned in closer. The sensation sent shards of pleasure through you, but you managed to focus on not letting go just yet.

"Shhh... be strong," Anais whispered in your ear, her voice low and soothing despite the tension growing between the two of you. "I know it's hard but I need to make sure everything is alright down there." Her hand continued its gentle stroking up and down your length as she massaged your balls with her other hand, teasing you mercilessly with pleasure and pressure. You could feel your control slipping away, but somehow managed to cling onto it by a thread.

The scent of your arousal filled the air as you struggled not to release, pleading with Anais to let you cum. She could feel her own heart racing in her chest, her body aching with desire for you. But as the head nurse and someone who valued health above all else, she couldn't give into your request just yet.

"Not quite yet, my dear," she whispered, her voice shaking slightly from the effort of maintaining control. "I need to make sure everything is perfectly fine before we can move on." Her hand continued its relentless motion up and down your length, while the other squeezed and massaged your balls, eliciting gasps and moans from you that threatened to betray the silent contest of wills between the two of you.

The look on your face, the way you struggled to keep quiet, the sound of your heart racing... all of it sent a thrill coursing through Anais's body. But she held firm, her fingers still moving with expert precision up and down your length, her thumb circling the sensitive tip. "That's my good boy," she praised you, her voice a mixture of affection and desire. "Now let's see how much longer you can last..."

Her free hand slid up your body, cupping your cheek before tracing a path down over your chest, across your abdomen and back up again, teasingly close to the rapidly hardening tip of your cock but never quite touching. The sensation only added to the tension building within you, making it feel like your entire body was on fire with desire.

The sound of your cries filled the room as you pleaded with her to let you cum. Her fingers, still moving expertly up and down your length, tightened ever so slightly as she felt yourself starting to lose control. She knew that if she let go now, it would only be a matter of seconds before you came all over her hand.

"I'm almost done," she whispered into your ear, her breath hot against your skin. "Just hold on a little longer..." Her other hand cupped your cheek once more, stroking gently across your jaw as she looked deep into your eyes, searching for any sign of submission in them.

Her heart raced as she felt your body tremble beneath her touch. The sound of your pleas echoed in her ears, each syllable a knife twisting deeper into her heart. She knew that she had to remain strong, for both of their sakes. But it was becoming increasingly difficult to ignore the aching desire growing within her as she watched you struggle.

"Almost there," she managed to croak out through a throat gone dry with need. Her hand sped up slightly on its journey up and down your length, her thumb brushing teasingly against the sensitive ridge of your head before sliding back down again. "Just a little longer..." The tip of her tongue flicked out to moisten her lips, unconsciously mirroring the motion as your hips bucked involuntarily beneath her touch.

Her eyes locked onto yours as your body arched and convulsed beneath her touch. "You're doing so well," she whispered hoarsely, her voice thick with desire as she watched the tip of your cock flush a deep red with need. She could feel herself growing wet at the sight, her own arousal threatening to overcome her professionalism.

But she couldn't give in now; not yet. Her fingers continued their steady pace up and down your length, as fast as they dared without causing discomfort or pain. "Almost there..." She breathed, her thumb moving back and forth over the tiny slit at the top of your cock, teasing the head with every pass.

The tension between them was palpable, electricity crackling in the air as they struggled against each other for dominance. But even as she fought to maintain control, a small part of Anais knew that it was only a matter of time before she surrendered to the inevitable.
